10.9
PORTH is an 8-bit wide, bidirectional I/O port. The
corresponding Data Direction and Output Latch registers
are TRISH and LATH. All pins are digital only and
tolerate voltages up to 5.5V.
All pins on PORTH are implemented with Schmitt
Trigger input buffers. Each pin is individually
configurable as an input or output.
All PORTH pins are multiplexed with LCD segment
drives controlled by the LCDSE5 register. I/O port
functions are only available when the segments are
disabled.
